just VS You-Dont-Need-Lodash-Underscore

You can roll your own or use a utility library. A simple zero-dependency library would be something like just-group-by [1]. Although I now prefer remeda [2] as it seems to have the best typescript support, especially the strict variants such as `grouBy.strict`.

Tree-shaking doesn't help much when the tree-shaken implementation is so bloated.

Here's the one you referenced, lodash.chunk: https://unpkg.com/lodash.chunk – 140 lines after removing comments and whitespace.

That's pretty small compared to a lot of the lodash utilities. Try spot-checking a few on unpkg.

I prefer angus's `just` utilities: https://github.com/angus-c/just

I absolutely love this. When I need some Lodash alternative I'll usually reference angus-c/just but I am definitely bookmarking this for next time.

The just set of utility functions are really nice to use. https://github.com/angus-c/just

Just doesn't have everything but it's pretty good

One of my favourite "libraries" are the "just" packages, where each part of the library is it's own simple package with zero dependencies (https://github.com/angus-c/just) so you essentially just npm install the specific thing you want - which is generally a single function.

If the code should, as you say, be 5 lines, why take on a dependency at all? By doing so, you end up with a catch-all solution that does almost nothing other than JSON.stringify your args, which is extremely poorly optimized to handle many situations, e.g. one of your args is a primitive and the other is a large config object.

These are all really outdated tips. Moment is deprecated and it is recommended to use dayJs or date-fns. Lodash is discouraged because it has a huge bundle size and nowadays you will find native functions which do most of the things people have used lodash before. https://github.com/you-dont-need/You-Dont-Need-Lodash-Underscore

I never used lodash but I found this. Might interest you.

In one of my team's Pull Requests I noticed date-fns being added as dependency for our components library for one usage: transform a timestamp to "MM/yy" string, as it represented a debit card's expiration date. Inspired by You don't (may not) need lodash/underscore, I thought to myself - can't we just implement a 2-digit month and 2-digit year formatting? It looks simple, right?

Yes and no. We did but are converting to in-house code since most Lodash functions are already available as native JS and/or @babel/preset-env + core-js@latest (see: You don't need Lodash).
